represent symbolic toolbox as a string

I am using the symbolic toolbox in Array1. How do you represent it as a string?

syms r,theta,phi

x=r*cos(theta)*cos(phi)

y=r*sin(theta)*cos(phi)

z=r*sin(phi)

Array1=num2str([x y z])

try this:

syms r theta phi
x=r*cos(theta)*cos(phi)

y=r*sin(theta)*cos(phi)

z=r*sin(phi)

Array1 = char([x y z])

Is this how you write a string from Array1?

for i=1:4

      for j=1:4

          for k=1:4

              string1(i,j,k) = 'Array1(' & i & ',' & j & ',' & k & ')' & char(Array1(i,j,k))

          next

      next

next

if you want to extract string from array then it will be better to save the string in cell array as follow:

syms r theta phi
x = r * cos(theta) * cos(phi);
y = r * sin(theta) * cos(phi);
z = r * sin(phi);
Array1 = {char(x), char(y), char(z)};

Now you can extract all three string as follow:

Array1{1} % 1st string
Array1{2} % 2nd string
Array1{3} % 3rd string

n=0;
  for l=1:4
      for k=1:4
          for j=1:4
              for i=1:4
                  n=n+1;
                  Array2(n)=char(Array1(i,j,k,l));
              end
          end
      end
  end

??? In an assignment A(:) = B, the number of elements in A and B must be the same.

Error in ==> matlab at 57 Array2(n)=char(Array1(i,j,k,l));

How do I get a sequential printout of an array?

you can do it as follow:

syms r theta phi
x = r * cos(theta) * cos(phi);
y = r * sin(theta) * cos(phi);
z = r * sin(phi);
Array1 = {char(x), char(y), char(z)};
% Print string on command window
for i = 1:3
    fprintf('String number %d is: %s\n', i, Array1{i})
end

Change

Array2(n)=char(Array1(i,j,k,l))

to

Array2{n}=char(Array1(i,j,k,l))
